Concrete aggregates are suitable for high-specification projects that require low water absorption and high strength. They are available in course or fine grades.
Coarse aggregate is available in 4-20mm sizes. It is a low shrinkage, low water absoring, high strength aggregate with a bulk density of 1.4 tonnes per cm3. It will produce more concrete per tonne than other commonly used aggregates.
Fine aggregates and sand are also available for concrete. Cloburn sand is produced from the finest quality granite and will make the finished product structurally sound with a high wear resistance. Concretes produced from Cloburn fine aggregates and sands are suitable for concrete floors, roads and dock areas.
As well as having low water absorption and high strength, Cloburn concrete aggregates are also freeze-thaw and shrink-resistant, with low chloride and sulphate contents.
